This comment was made by Chase, copy and pasting here: The log shows that the headset is sending a button 3 press event for the entire duration that it is plugged in. Here's the relevant log lines, with many lines in between omitted:

The Evdev input module interprets the device as a keyboard. Thus, when you plug in the headset it's as though you have a second keyboard connected where a key is stuck pressed. This interferes with normal X keyboard event handling. This either needs to be handled by quirking the HID driver in the kernel so that it knows not to expose this bad behavior, or by quirking the X evdev input module so that button 3 is ignored from this device. I think the correct approach is to quirk the kernel HID driver, but I'm not sure. I suggest contacting the upstream linux-input mailing list for advice. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1007575 Title: SB Arena USB headset causes X BUG, can't click outside window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1007575/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
